For two miles it preserved a pretty general width of from twenty to thirty yards; but at that distance began to narrow, and at length it became quite shallow and covered with weeds.

We were ultimately obliged to abandon the boat, and to walk along a native path.
The country to the westward was more open than I had expected.

About a quarter of a mile from where we had left the boat, the channel separated into two branches; to which I perceived it owed its formation, coming, as they evidently did, direct from the heart of the marsh.

The wood through which I had entered it on the first occasion bore south of me, to which one of the branches inclined; as the other did to the S.W.An almost imperceptible rise of ground was before me, which, by giving an impetus to the waters of the marsh, accounted to me for the formation of the main channel.

It was too late, on my return to the camp, to prosecute any further examination of it downwards; but in the morning, Mr.Hume accompanied me in the boat, to ascertain to what point it led; and we found that at about a mile it began to diminish in breadth, until at length it was completely lost in a second expanse of reeds.
